The method includes: detecting the busbar voltage of the air conditioner, and determining whether the busbar voltage of the air conditioner is greater than a preset magnetization voltage entry value, and the preset magnetization voltage entry value is smaller than the overvoltage protection value of the air conditioner; if the busbar voltage of the air conditioner is determined is greater than the preset magnetization voltage entry value, set the first direct axis current command value of the permanent magnet synchronous motor to the pre-stored current value, and the pre-stored current value is greater than zero; obtain the target speed of the permanent magnet synchronous motor, and according to The target speed and the first direct axis current command value are used to drive the permanent magnet synchronous motor, so that the permanent magnet synchronous motor works in a motoring state. The invention is suitable for the technical field of air conditioning.
